Interesting side question. I was lead to believe my late 2008 MBPro =
(which according Apple doesn't support more than 4GB) needs the 64 bit =
kernel to run with more. I haven't tried though.

That said, I don't think if it is or is not necessary is really that =
relevant. Running the 64 bit kernel has other performance benefits, so =
is desirable. Also I believe the latest Mac Pros now use the 64 bit =
kernel by default... The 64 bit kernel is the way of the future, so I =
think it best OpenAFS works out any niggles it has with it as soon as it =
can ... Just my opinion ...
